Hello,

Recently I bought back my first car back from my Dad / Step Sister, a 2003 Cavalier LS Automatic. It's bone stock and they managed to rack up a few miles in the 2 years they had it.
My question is, what can I do in terms of maintenance and modifications to make it a stronger and more stable car before I even think about boosting performance?
What can I do to prepare the car to handle more power? Should I do something to the frame, or just the suspension? I'm pretty new to working on cars in general, so if
you think something is pretty obvious or that I should already know please post anyway, I appreciate learning every little thing I can.

Thank you
